I-Acrylonitrile ye-NBR,
I-Acrylonitrile ye-NBR Nitrile, i-Acrylonitrile ye-Acrylonitrile Butadiene Rubber, i-Acrylonitrile yerabha ye-Nitrile,
I-NBR (Nitrile), ngamakhemikhali, iyi-copolymer ye-butadiene ne-acrylonitrile.Okuqukethwe kwe-Acrylonitrile kuyahlukahluka emikhiqizweni yokuhweba kusuka ku-18% kuya ku-50%.Njengoba okuqukethwe kwe-NBR kukhula, ukumelana nowoyela wesisekelo se-petroleum namafutha e-hydrocarbon kuyanda, kodwa ukuguquguquka kwezinga lokushisa eliphansi kuyehla.
Mayelana ne-NBR
Ngenxa yokumelana kwayo okuhle kakhulu nemikhiqizo ye-petroleum, kanye nekhono layo lokuhlanganiswa ukuze isebenze ngaphezu kwezinga lokushisa eliphakathi -35°C kuya +120°C (-30°F kuya +250°F), iNitrile/NBR iyona ebanzi kakhulu. esetshenziswa i-elastomer embonini yezimpawu namuhla.Futhi imininingwane eminingi yenjoloba yezempi ye-O-rings ukumelana nowoyela kudinga amakhompiyutha asekelwe ku-nitrile.
Kufanele kukhulunywe ukuthi ukuze uthole ukumelana okuhle nokushisa okuphansi, ngokuvamile kudingekile ukudela ukumelana nokushisa okuphezulu.Izinhlanganisela ze-nitrile ziphakeme kunama-elastomer amaningi ngokuphathelene nokucindezelwa kwesethi, ukudabuka, nokumelana nokuhuzuka.Izinhlanganisela ze-nitrile azikwazi ukumelana ne-ozone, ukukhanya kwelanga, noma isimo sezulu.Akufanele zigcinwe eduze kwezinjini zikagesi noma ezinye izinto ezikhiqiza i-ozone.

I-Acrylonitrile ikhiqizwa ukuthengisa nge-propylene ammoxidation, lapho i-propylene, i-ammonia, nomoya kusabela nge-catalyst embhedeni omanzi.I-Acrylonitrile isetshenziswa ngokuyinhloko njenge-co-monomer ekukhiqizeni imicu ye-acrylic ne-modacrylic.Izinto ezisetshenziswayo zihlanganisa ukukhiqizwa kwamapulasitiki, okokugcotshwa okungaphezulu, ama-nitrile elastomers, ama-barrier resins, nama-adhesives.Iphinde ibe yikhemikhali emaphakathi ekuhlanganisweni kwama-antioxidants ahlukahlukene, amakhemisi, odayi, kanye ne-surface-active.
1. I-Acrylonitrile eyenziwe nge-polyacrylonitrile fiber, okuyi-acrylic fiber.
2. I-Acrylonitrile ne-butadiene ingenziwa i-copolymerized ukuze ikhiqize irabha ye-nitrile.
3. I-Acrylonitrile, butadiene, styrene copolymerized ukulungiselela i-ABS resin.
4. I-Acrylonitrile hydrolysis ingakhiqiza i-acrylamide, i-acrylic acid nama-esters ayo.
